Door-buster fares include $98 round-trip flights between Boston and destinations such as New York, Houston, and Atlanta. Round-trip flights between Philadelphia and Fort Lauderdale can be had for $118 while a round-trip ticket between New York and Palm Springs is just $138.

The always popular round-trip between New York and San Francisco costs as low as $268. It's not as cheap as the others, but still a significant discount over non-sale fares.

However, there's some fine print to navigate.

JetBlue.comTickets must be purchased before midnight eastern time on Wednesday, Nov. 29. In addition, flights on Friday and Sunday are not included. All tickets must be for travel from Dec. 5 through Dec. 14, and from Jan. 11 through Feb. 14, 2018.

This is isn't the first time JetBlue has offered such low prices. In October, the New York-based boutique carrier made news by offering round-trip tickets for as low as $62. However, this sale does offer more flight options.
